To a/Z whom it may concern:`

Be it known that I, JACKSON B. YOUNG, a citizen ofthe United States, residing at Sioux Falls, in the county of Minnehaha and Territory of Dakota, have invented new and useful Improvements in Time-Locks, of which the A'following is a specification.

This invention relates to that class of time-V locks in which a single time-movement is employed to determine the ti me at which the 4lock may be unlocked. Y

The object of this invention is to producea time-lock of a construction to prevent unlocking when the timer is running, and capable of adjustment to stop the movement at any predetermined tiine within the running-time of the movement, and to permit unlocking when the movement is not ruiming; and it consists, mainly, in the combination of a time-movement with the tumblers of a permutation-lock to prevent their adjustment for the purpose of unlocking, and in combination with the movement of a stop mechanism 'capable of adjustment to stop the movement at any predetermined time .within the running-time of the timer; in mechanism to adjust the timerin its connection with the lock to regulate its operative force within the capacity of the movement. These, including the mechanism employed, and other improvements, to be hereinafter more fully described, constitute the subject-matter of this specitication.

In the accompanying drawings, Figure l is an inner face elevation of a mechanism embodying my invention. Fig. 2 is an edge elevation. Fig. 3 is an isometrical inner face representation, partly in skeleton, of the main portions of my improvements. Fig. 4 is an elevation of the stop mechanism; and Fig. 5 is a vertical central section of mechanism employed to adjust the timer to the locking mechanism.

In the figures I have represented a base.- plate or a portion of a wall on which to mount a lock, and a timer in connection therewith, to illustrate my improvements; and for this purpose in this instance I have selected a wellknown form of a four-tumbler permutationlock and an ordinary time-movement. These I have mounted on the base-plate A. The lock employed consists of the tumblers ci, b, c, and d, of disk forni, each provided with a radial slot, e, opening through their periphery to receive the locking-bolt. These several tumblers are supported in a frame fixed to the base-plate, and the tumbler a is connected with a graduateddisk, B, on the outside of the base-plate or wall A, by means of a spindle extending through the base-plate or wall in such a manner that the rotations ofthe graduated disks B will be imparted to the tumbler a. This tumbler c and the tumbler'd on their inner-face sides, and the tumblers b and c on both face sides, are provided with screw-studs Il, projecting therefrom On lines having the same diameter, in a manner to engage each other when the graduated dial is rotated.

At C is represented a locking-bolt capable of an endwise sliding movement in guideways. This locking-bolt is provided with an arm, D, ttcd to enter the radial slots in the tnmblers when they are adjusted to bring their radial openings in position to receive it. These several parts are substantially the same as like parts of locks now in use, and are operated in the same manner, and capable of like adjustments for like purposes.

Atiis represented a segment-block of proper dimensions, fixed to the outer face of the outer tumbler-in this instance near its peripheryand about a quadrant distant from the radial slot therein and rearward thereof relatively with the direction of rotation in picking up the tumblers preparatory to their adjustment for unlocking. Instead of this segment-block a pin, peripheral or side enlargement of the tumbler may be employed.

y In combination with this lock I have employed an ordinary time-movement consisting of a mainspring, E, and the usual geartrain, in connection with an escapement and balance wheel mounted in a suitable frame. In this movement I have provided a frictionwheel, la, mounted loosely on a shaft of the gear-train to engage a collar, 7c', fixed on the shaft, against which it is held with a force sufficient to produce the required friction by means of a spring, k", surrounding its shaft. The periphery of this friction-Wheel 7c and the periphery of the segment-block 'i are provided IOO with roughened or corrugated surfaces to engage each other; butinstead thereof they may be produced in even plain frictional surfaces, orthey may be produced with corrugated surfaces to engage each other in gear-toothed form to increase their frictional contact or holding force. This movement is mounted upon the bed-plate or wall on suitable supports, F and H, in such position relatively with the lock that the periphery of the friction-wheel shall be in position to engage the periphery of the segment fixed to the outside face of the tumbler. This movement in its connection with the bed-plate is made adjustable towardd and from the lock, for the purpose of regulating the holding force between the friction-wheel and the segment. For this purpose I have produced the slot Z in the movement-frame to engage the stud-support F, to permit of a limited adjustment.

At. Zis represented a burrnuthavingascrewthread connection with the outer end of the stud-support F, to fix the movement-frame to the stud-support. y

At I is represented an adjusting-screw having a screw-thread connection with the studsupport F, and its sliaftis connected with the movement-frame by means of the slotted arm m, projecting threfrom and embracing the shaft between the collars m', iixed thereto. By means of this adjusting-screw and the burrnut in their connection with the movement and its supports, the movementis made readiiy adjust-able toward and from thev lockto regulate the holding force of the friction-w heel and segment.

From the foregoing it will be seen that in picking up the tumblers preparatory to their adjustment for the purpose ot' unlocking, the segment may be carried over the frictionwheel,which, by reason ofits loose connection with its shaft, will revolve thereon Ywithout stopping the movement.

ln the adjustment of the tumblers by means of the graduated disk B, for the purpose of unlocking, the inner tumbler, d, is the first of the series to be brought into position to receive the arm D of the bolt in its radial slot. The arrangement of the parts are suchv that in this adjustment, when thetumblerd is brought into position to receive the arm D of the bolt the segment will have engaged the frictionwheel in such a manner that when the tumbler is released from the action of the graduated disk, as in the adjustment of the other tumblers in the series, the movement of the timer will have carried the tumbler d from its adj usted position to the position shown in the dotted lines at Fig. 3 before the other tumblers can be adjusted, from which it will be seen that my improved time-lock cannot be opened while the time-movement is running. This construction and arrangement requires that provision be made for stopping themovement at the time xed upon for opening the lock. For this purpose l have provided the following mechanism:

At K is represented an angle-lever detent having apivotal connection ata with the movement-frame in such position thereon that its angle-arm a when thrown forward, as in Fig.

4, will engage the teeth of one of the gearwheels in the gear-train of the movement. This detent-lever is provided with a spring, n, having a pivotal connection at one end with the detent-lever, and its other end is pivoted to the movement-frame. The connection of these parts are such that when the free angle-arm of the detent is carried to the right-hand side of a vertical line cutting the pivotal centers ot' the lever-detent and the spring in their connection with the moven'ient-frame, the lever-detent will be thrown bythe action ofthe spring tothe righthand side of the line until its depending arm a engagesthe pivotal connection of the spring with the frame. If the free angle-arm of the detent-lever is carried to the lett-hand side of the line ot' the pivotal centers of the vdetent and spring with the movement-frame, the spring action will carry the free arm of the lever to the left-hand side,and cause its anglearm to engage the teeth of agear-wheel of the gear-train, as shownin Fig. 4., and stop the movement. This detent lever is provided above its pivotal connection with oblique tappet-arms 0 and o', rising from its outer face.

At p is represented a gear-toothed pinion mounted upon the projecting end ottliespringshaft p.

At N is represented a gear-toothed wheel having its journal-support on the frame ot' the time-movement in such position thereon that its teeth shall engage the teeth of the geartoothed pinion p. The rim of this gear-wheel N is provided with a series ot holes, p, in close proximity, in an annular ring within, but near the base of, its gear-teeth.

At t is represented an index-arm pivoted on the axial center of the gear-wheel N ina manner to permit of a rotary or oscillating movement independent of the wheel for the purpose of adjustment. The outer portion of this arm is provided with astud-pin, t', lprojecting from its inner face in position to enter the holes p in the rim of the wheel, and extend beyond its under face in position to engage the tappetarms 0 and o of the detent in its rotary or oscillatory movements. The construction of these parts is such that when ythe detent-lever is in its positiomdisengaged from the gearwheel of the movement, the rotation of the gear carried by the time-movement in the direction indicated by the arrow, the stud-pin t Will pass over the outer end ofthe right-hand tappet-arm, o', and engage the left-hand tappet-arm, o, and carry the detent to engage the gear wheel of the train and stop the timemovement. In winding the spring the gear-wheel N will be made to rotate in the opposite direction to that indicated by the arrow thereon, which movement will carry the stud-pin over the outer end of the left-handtappet-arm,o,to engage the right-hand tappet-arm, o', and disengage the detent from the gear-wheel of the train and permit the running of the movement.

At I? is represented a dial of annular-ring form mounted over the gear-Wheel N,Iconcentric thereto, on suitable supports rising from the frame ofthe gear-train. This dial in this instance is graduated into forty-eight main divisions, corresponding to the hour-divisions of the llimer, and these in this instance are numbered from, 0, the zero-point, toward the right hand to 47. These main divisions vare divided centrally, representing half-hours, but may loe subdivided into any practical numberV of parts required to indicate any required division of the hour. armt is produced in pointed-nger form to more readily determine its position of adjustmenton the dial. The position of the 0 or zero-point of the dial relatively with the detent is such that when the index-finger has reached the O or Zero-point the stud-pin t will have carried the detent beyond its pivotal center, and the detent Will have engaged the teeth of the gear-Wheel and stop the time-movement.

To determine the position of the index-iinger relatively with the dial to stopthe timemovement at a predetermined time for the purpose of unlocking, the number of hours between the time the adjustment is made,and the time fixed upon for unlocking must be reckoned, and the number obtained by this reckoning found upon the dial is the point on the dial to which the index-finger must be adjusted to stop the time-movement at the predetermined time. This adjustment is accoml The outer end ofthe indeX- plished by lifting the stud-pin t' from its connection with the dial, and carrying itV to the required point thereon, and inserting the stud-pin in the proper hole in the gear- Wheel. For this purpose the index-arm is made from suitable material and in a proper manner to permit of the Withdrawal and reinsertion of the stud-pin at any point on the dial; and it is provided toward its outer end with a stud-knob, t, as a ready means by which to adjust the arm. In this instance I have connected with the time-movement the lock tumbler farthest from the operating graduated disk, and have connected this tumbler With the fourth Wheel of the gear-train of the movement; but instead thereof any one or more than one of the tumblers may be conl nected with the movement, and such connection may be made with any portion of the timemovement which will be efficient in moving the tumbler in the manner and for the purpose hereinbefore stated.
